Communication machine room cooling system

Abstract

The invention discloses a communication machine room cooling system which comprises an internal circulation cooling medium providing loop, a medium natural cooling loop and a central temperature control unit, wherein the internal circulation cooling medium providing loop comprises an internal circulation duct, a chilled water cooling heat exchanger, more than one partial hot position gas-liquid heat exchanger, an internal circulation water pump and a natural cooling heat exchanger; the chilled water cooling heat exchanger is connected with a chilled water duct and exchanges heat through an automatic regulating valve; the partial hot position gas-liquid heat exchanger is arranged at the hot air outlet of each electronic device; the internal circulation cooling medium providing loop exchanges heat with the medium natural cooling loop through the natural cooling heat exchanger; the medium natural cooling loop comprises an external circulation duct, an external natural cooling device, an external circulation water pump and an automatic regulating valve; and the central temperature control unit is connected with temperature sensors and regulating valves.

Description

technical field [0001] The invention relates to a cooling system for electronic equipment in a communication machine room. Background technique [0002] The communication room, such as the data center room, is a place where electronic equipment is placed. When the electronic equipment is running, it will generate more heat. In order to ensure that the electronic equipment works under normal working conditions, the data center is generally equipped with a special air conditioner. temperature, thereby ensuring the working conditions of electronic equipment. However, with the rapid development of electronic technology, the integration of electronic equipment is getting higher and higher, and its heat density is also getting higher and higher. Placing these high-density electronic equipment in the data center will generate a large number of local hot spots in the data center . [0003] Generally, the optimal temperature for electronic equipment in data centers is 23°C. In orde...

Problems solved by technology

However, when there are local hot spots in the data center, if the cold air sent by the air conditioner is only slightly lower than 23°C, it cannot meet the heat dissipation requirements of the electronic equipment in the local hot spot area.

In order to meet the heat dissipation requirements of electronic equipment in local hot spots, it is necessary to lower the temperature of the cold air sent by the air conditioner, or increase the air supply volume of the air conditioner, which will lead to an increase in energy consumption of the air conditioner

[0004] Therefore, if the problem of local hot spots in the data center is not solved, the energy consumption of the air conditioner will be very large, which is not conducive to the energy saving of the data center
